I've seen some sending units fail due to an internal "open" circuit for the fuel pump. Check for power getting to the sending unit for the fuel pump. If that's good, check the ground. With that, the fuel pump should run. If not, either the pump or the sender is bad. You'll have to pull the sending unit, either way. Check for continuity through the sending unit.
